The commercial and government fleet members of the Chicago Area Clean Cities saved more than 25 million gallons of petroleum in 2014, which reduced fuel consumption and improved air quality, according to the group.

Waste Management has opened a public-access compressed natural gas (CNG) fueling station in Southern California to refuel Waste Management’s local fleet and sell CNG to commercial fleets and consumers.

TransForce CEO Alain Bédard said the Montreal-based company will spin-off the truckload business, possibly in 2015, followed by the waste division, which includes landfills, possibly a couple years later.

At a time when many shippers have chief sustainability officers and government contracts are requiring low-emissions or alternative-fuel equipment, some fleets are finding it pays to have natural gas trucks in their arsenal.

Waste Management announced it is building a facility that will create pipeline-ready natural gas from its Milam Landfill in Fairmont City, Ill. The processed renewable natural gas will be injected into the pipelines of Ameren Illinois for withdrawal at other locations, including some Waste Management facilities.
